To `all whom t may concern:

-Be it known that I, GEORGE L. SIMPSON,

residing at State of California, have invented new and useful Improvements in N onskid Sectional Tire Treads, of which the following 'is a specification. 1

This invention relates to antislnd treadsy lfor pneumatic tires which include a plural- `ity lof tread members preferably formed from old tire casingsand received around -the tread of the tire with lookin means connecting the respective antiski tread sections.

The present invention provides improved means for securing together the tread sections so as to provide an eicient construction, but one whichis simple and inexpensive to manufacture;

The invention will be readily understood from the following description of the accompanying drawings, in which: l

igure l is a side elevation of a tire showing the improved antiskid sectional tread applied thereto.

Fig. 2 is an edge view of the same. Figs. 3 and 4 are detail sections on the lines 3--3 and 4 4 of Fig. l.

Fig. 5 is a transverse section onl the line 5 5 of Fig. 1.

Fig.- 6 is ap'detail section through one of the clamping members. and taken on the line Fig. 7 is a side elevation of this clamping member. v Y

` The improved tread structure is employed in connection with a usual pneumatic tire mounted upon the rim 1 and including a tire casing 2. A plurality of sections form the tread received over the tread of casing 2, and said sections may be sections of a worn out tire casing, asshown at 3. These sections are received over the tread of tire casing and are -provided with improved detachable connecting means for connecting the same in position.

The connecting means includes two wires each formed as a loop with-the respective strands of said loops as shown at 4, received against opposite surfaces of the tread sections 3 and extending around the plurality of tread sections justabove the beads 3l at the ends of said tread sections. Each of the wires thus connect approximately one- -half of the tread sections received around seal No.' 468,502".

wires are positionedadjacentone an'ot er between adjacent tread sections 3 andare twisted to form a co-operating hook and ieye 5 and 6 adapted to be received one'with- 1n the other so as to detachably connect the wires.

l The ends of the looped wires which extend aroun'dthe tire overlap and are provided with clamping means engaging said wlres so as to connect the strands ofthe respective wires and also connect one wire to another. These clamping means are preferably arranged between several of adjacent tread sectlons and are shown as co-operating Specification Letters Patent. Paiitedg'l' 10, 1922. Y.

angle clips 7 arranged to engage the strands of both wlres'between the same with a usual l bolt Sandnut 9 functioning to connect the angle cllpsand clamp thevsame upon the wires.

The two strands of each looped wire are preferably also connected between each of adjacent tread lsections as by wrapping a wire lO'around said strands and-in the spaces between tread sections.I

The construction, as thus described, provides means for connecting the fastening wires `firmly to the tread sections, and for also detachably connecting the respective looped wiresin order that the tread for the tire which is'thus formed may bev readily removed or replaced in position.

-Various changes may be made without departing from the spirit ofthe invention as claimed. What is claimed is:

1. The combination with a tire of a tread comprising tread sections, and vconnecting mea-ns for said tread sections, fincludingj looped wires each received around a portion of the tire and alongside of the respective surfaces of a part of said tread sections and adjacent the ends of the'y same, fastening wirescoiled about said wire loops between said tread sections, the ends of said looped wires overlapping, and clamping means engaging thestrands of said looped wires at said overlapped ends and between adjacent tread sections for spacing the latter.

2. The combination with a tire of a tread comprising tread sections, and connecting means for said tread sections, including looped wires each received-around a portion of the tire and alongside of the respective surfaces of a part of'said tread sections and adjacent the ends of the same, said loops surfaces of a part of'sad tread sections and` adjacent the ends of the same, said loops formln detachable connecting means be tween t e same, the endsof said looped wires overlapping, clamping means engaging the strands of said looped wires at said overlapped ends-and between adjacent tread sections for spacing the latter, and coils of wire for connecting the strands of each loop be' tween adjacent tread sections so Vas to space said tread sections. In testimony whereof I have signed my name to this specification..
